93. Prince, 'Sign 'o' the Times'

Paisley Park, 1987

The most expansive R&B record of the Eighties is best known for the apocalyptic title track, the funk banger "Housequake" and the gorgeous "If I Was Your Girlfriend." Yet the simplest moments are unforgettable: the guitar plea "The Cross" and the Stax revamp on "Slow Love."
